The religious and cultural definition requires Pashtuns to be Muslim and adhere to Pashtunwali codes. This is the most prevalent view among orthodox and conservative tribesmen, who refuse to recognize any non-Muslim as a Pashtun, even if they themselves claim to be of Hebrew ancestry as some tribes do. Pashtun intellectuals and academics, however, tend to be more flexible and sometimes define who is Pashtun based on other criteria. Pashtun society is not homogenous by religion: the overwhelming majority of them are Sunni Muslims, with a tiny Shia community (the Turi and partially the Bangash tribe) in the Kurram and Orakzai agencies of FATA, Pakistan. Pakistani Jews and Afghan Jews, once numbering in the thousands, have largely relocated to Israel and the United States
